Application filed hpril 18, 1936.

To all whom it may concern '1 Be it known that 1,,GEORGE W. BRETZ, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Attachments for Cameras, of which the-following is a specification.

This invention relates to a new and usefu improvement in an attachment for cameras and pertains more particularly to an at tachment provided for the purpose of forming legends or titles on the filmsby a photo graphic process.

Another feature of the invention resides in the provision of means for positively excluding light from the film, excepting at the instant when the process of photographing said legend or title'takes place and of admit ting the light at the desired time.

With the above and other objects in view the invention has particular relation to certain novel features ofconstruction, operation and arrangement of parts, an example of which is given in this specification and illustrated inthe accompanying drawings, wherein Figure 1 shows a side elevation of a cam-- era,

Fig. 2 shows a similar, view' 'ther eof with the near wall removed,

Fig. 3 shows a fragmentary plan view of a camera showing the attachment in position for receiving the title or legend,

Fig. 4 shows a longitudinal sectional view thereof taken on the line a-a of Fig. 3,

Fig. 5 shows a fragmentary plan view of the camera showing the positions the parts will assume when the title or legend is in position to be photographed upon the film,

Fig. 6 is a transverse sectional view taken on the line 7)7) of Fig. 5,

receiving member 3 and of admitting light for photographing the title on the film at the prop-er time; This complete attachment is carried by the camera wall and is lnclosed by means of a plate l, the middle part of which is formed into an inclosing hood 5 having an oblong opening 6 therethrough for a purpose to be hereinafter stated. Upstanding plates 7, 7 are provided and formed, with respect to the bottom thereof, so as to provide receivinggrooves 8, 8 in which the shutter plate slides. This plate is provided ,with an oblong window 10, which is out theret-hrough and has also the shutter lhhiiiged to the plate and normally closing said ,window. The shutter is held in closed position by means of the flat spring 12, one end of which is anchored to the plate 9 and the free end of which rests against said shutter and the hinged edge of the shutter has an upstanding stud 13 fixed thereto, the purpose of which will hereinafter he described.

T he title receiving member 3 is provided at its ends with the arms 1%, 14 which have bearing pins 15 15 projecting through alined slots, as 16, in the respective plates 7 and provide sliding bearings for said vtitle receii ing member and pull springs 17,, 17 are provided whose ends are attached, respectively, to the plate 9 and pins 15, 15. A pair of links 18, 18 are provided, each of which is pivoted at one end to the plate 9, and at the other end to the corresponding arm 14 between its bearing and the member 3.

Behind the opening 2 and extending from end to end of the hood 5 is an apron 19, the

upper edge thereof falling short of the top of the hood to provide a light window which is normally closed by means of the oblong This shutter has the end bearings 21, 21, which are pivoted to the plates'i, 7, by means of bearing pins 22, 22, and it is normally held in closed position by means of springs as which are coiled around the respective pins 22 and whose ends are free and press against the respective studs 24 and 25, whichproject from the adjacent plates 7 and the corthe fingers thereof emln'acing the pin 31 which depends from the finger 32 upstanding from the plate 9, while the other end of the lever 27 projects behind the stud 13 and when manipulated contacts with said stud to open the shutter 11.

A short shaft 33 has a bearing in the camera wall and its outer end has the thumb grip 3%. Fixed to the inner end of this shaft is the cam whose free end carries the pin 36, which projects through the slots 30 and29. v

The member 3 is formed of ground glass and the title or legend which it is desired to transfer to the film may be written thereon with the ordinary pencil or other similar means when the member is projected through the window 2, as shown in Figs. 1 and 7. Assuming this member is in the position shown in Fig. 7, the mechanism will occupy the position shown in Fig. 3 and the indicator 3?, shown in Fig. 1, will indicate open position. The thumb grip 34 may then be turned in the direction indicated by the arrow in Figs. 1 and 3 and the pin 36 moving through the slot 29 ofthe lever 26 will manipulate said lever, moving the plate 9 laterally and carrying the shutter 11 toward said window 2. While this movement is taking place the linkslS. 18 will operate agail'lst the corresponding arms 1-l, Li and simultaneously therewith the pull springs'l'i', 17 will operate to hold the bearing pins 15, 15 against the lower ends of the slots 16,- causing the member 3 to be withdrawn from the window and to swing around on said bearing pins. Meanwhile, the shutter 20 remains closed until the fingers 38, 38, carried by the outer ends of the pins 15, 15, contact against the end bearings 21, 21 of the shutter 20 and force said shutter open. Before this shutter is opened. however, the plate 9 has closed the window 2. excluding all light and as the movement of said plate continues the member passes through the light window. whicl has been opened by the shutter 20. and is projected through the opening 6 and rests against the film 39, as shown in Fig. (3. The slot 30 is eccentric with respect to the slot 29, forming in effect. a cam 40, carried by the lever 27 and when the member is seated against the film the pin 36 contactsagainst this cam 40, forcing the opposite end of the lever 27 outwardly against the stud I? and opening the shutter 11 for an instant, the free end of the lever 27 passing over said stud into the position shown in dotted lines in Fig. 2

and the spring 12 then suddenly closing the shutter, thus admitting light through-the window 2, and the shutter 20 at this time being open, the title or legend on the memher 3 is photographed onto the film. For the purpose of restoring the mechanism to its original position a flat spring -11 is secured to the camera wall at one end and. its other end is pivoted to the link *2, which has a slot l3 throughwhich the pin 36 also projects. The tension. of the spring -11 is overcome when the thumb grip is turned, as hereinbefore indicated, the mechanism assuming the position shown in Fig. When the thumb grip is released this spring'l, operating through the link -12, carries the levers 26 and 27 back into intermediate position, withdrawing the member 3 back within the hood so as to clear the shutter 20 and releasing the fingers 38 from the bearings 21 with the result that the shutter 2018 released to the influence ot' the spring 23, and the shutter 20 thus closed. \Vhen in this position, the plate 9 will not be withdrawn far enough to clear the window 2 and said plate and shutter 20 will form a double protection against the admission of light. \Vhen it is desired to again expose the title member 3. the thumb grip 3-l may be manually turned to open position shown in Fig. 1 and the desired result will thus be accomplished.

It will be observed that the member 3 after it has received the legend or title, turns on its bearings and is in reversed po sition when it bears against the film. causing said title to photograph on the film the reverse of position it is written on said member. This movement is essentialinasmuch as the film images are reversed in finishing the final picture.
